The posix-man-page on setpgrp declares the setpgrp prototype as pid_t
setpgrp(void);, which makes this sort of weird I guess.

You could check if it worked to change the relevant function call from
setpgrp() to setpgrp(0, 0)? Just search for posix_setpgrp, and make sure
that the function isn't called with an empty argument list.

Though I believe this is something for the core python developers and not
for me to fix, or even advice in, so if you want to be on the safe side to
ensure no breakage, don't touch it on my advice.
